Default Compression test - need leakdown?

Compression tested my Miata today.

181, 180, 174, 180 dry.

Is a leakdown test a necessity? Or is the compression on the engine as is healthy enough to proceed with turbo'ing?

Note: The engine was replaced recently by a previous owner. Actual mileage is unknown, however, as the VIN on the engine doesn't match the car's VIN, it's a pretty damned good indicator that an engine was swapped on it. Components involved in the swap have very little wear or tear, I'd estimate at most a year or two since swap.

Are you kidding? Assuming you have confidence in those numbers, that engine is as healthy as could be! I've got > 30 PSI spread on the engine in the blue car, and even it still runs like a champ. (Granted, that would be a Special Olympics champ, but still...)

If it doesn't knock or smoke, than boost it. **** even if it does knock and smoke boost it then swap in a new motor.

My old 1.6L was like 210,210,180,210. And I still boosted it. And made decent power.

I may leak and put the compression tester on my daily today. It needs a rear main, hopefully I'm wasting my time so I have an excuse to put a 10:1, 0-mile motor in it.
